Examples

The following command requests statistics for an AutoBalance job with an ID of 6.

isi job statistics view --job-id 6

The system displays output similar to the following example. In the example, PID is the process ID, and CPU indicates CPU utilization by the job. Also indicated are how many worker threads exist for the job on each node and what the sleep-to-work (STW) ratio is for each thread. The statistics represent how the system throttles the job based on impact policies.
